Brother HL 4140, 4150, 4570 Fuser Assembly Removal and Reset Procedure
Fuser Assembly Removal and Reset Procedure for the Brother HL – 4140, 4150, 4570
As with most these fuser assembly removal instructions articles I’ve posted I’m not going to get into a lot of detail about the specific fuser errors and messages. This article is just about the removal and the reset of the counter for the fusing unit. Unlike previous higher end Brother printers these fusers are only rated at 60,000 prints. I think a lot of this has to do with the fact that often on the older models the fusing assembly would start having issues before the 80,000 life they were recommended at. Anyway, here is the fuser assembly removal and reset procedure. If you have problems with the pictures you can always click on them for a better view.
